Abstract

The gap between calculated and actual energy use has long be recognized as a major hurdle for a realistic assessment of buildings’ performance and anticipated benefits from energy conservation measures, especially when attempting a national building stock analysis. A multinational European effort to develop a conceptual framework for monitoring the effectiveness of energy retrofit measures applied in the European housing sector has motivated a number of national pilot actions. This paper presents the results from the work carried out in Greece and elaborates a methodology for deriving different empirical adaptation factors that relate the normative calculated heating energy consumption from energy performance certificates (EPC) with the actual energy use. To gain some additional insight, the work is complemented by evidence from field surveys to collect actual energy use data from dwellings before and after refurbishment and behavioural surveys of occupants. The derived factors are used to adapt the predictions, which are then organized according to the Hellenic residential building typology. The overall approach is used with a building stock model to demonstrate a preliminary assessment of different energy conservation measures, towards meeting the national targets for 2020 and 2030.
